BluetoothProfile

public interface BluetoothProfile

android.bluetooth.BluetoothProfile


Public APIs for the Bluetooth Profiles.

Clients should call BluetoothAdapter#getProfileProxy, to get the Profile Proxy. Each public profile implements this interface.

Summary

Nested classes

interface BluetoothProfile.ServiceListener

An interface for notifying BluetoothProfile IPC clients when they have been connected or disconnected to the service. 

Constants

int A2DP

A2DP profile.

String EXTRA_PREVIOUS_STATE

Extra for the connection state intents of the individual profiles.

String EXTRA_STATE

Extra for the connection state intents of the individual profiles.

int GATT

GATT

int GATT_SERVER

GATT_SERVER

int HEADSET

Headset and Handsfree profile

int HEALTH

This constant is deprecated. Health Device Profile (HDP) and MCAP protocol are no longer used. New apps should use Bluetooth Low Energy based solutions such as BluetoothGatt, BluetoothAdapter#listenUsingL2capChannel(), or BluetoothDevice#createL2capChannel(int)

int HEARING_AID

Hearing Aid Device

int HID_DEVICE

HID Device

int SAP

int STATE_CONNECTED

The profile is in connected state

int STATE_CONNECTING

The profile is in connecting state

int STATE_DISCONNECTED

The profile is in disconnected state

int STATE_DISCONNECTING

The profile is in disconnecting state

Public methods

abstract List<BluetoothDevice> getConnectedDevices()

Get connected devices for this specific profile.

abstract int getConnectionState(BluetoothDevice device)

Get the current connection state of the profile

abstract List<BluetoothDevice> getDevicesMatchingConnectionStates(int[] states)

Get a list of devices that match any of the given connection states.

Constants

Public methods

getConnectedDevices

public abstract List<BluetoothDevice> getConnectedDevices ()

Get connected devices for this specific profile.

Return the set of devices which are in state STATE_CONNECTED

Returns
List<BluetoothDevice> List of devices. The list will be empty on error.

getConnectionState

public abstract int getConnectionState (BluetoothDevice device)

Get the current connection state of the profile

Parameters
device BluetoothDevice: Remote bluetooth device.

Returns
int State of the profile connection. One of STATE_CONNECTED, STATE_CONNECTING, STATE_DISCONNECTED, STATE_DISCONNECTING Value is STATE_DISCONNECTED, STATE_CONNECTING, STATE_CONNECTED, or STATE_DISCONNECTING

getDevicesMatchingConnectionStates

public abstract List<BluetoothDevice> getDevicesMatchingConnectionStates (int[] states)

Get a list of devices that match any of the given connection states.

If none of the devices match any of the given states, an empty list will be returned.

Parameters
states int: Array of states. States can be one of STATE_CONNECTED, STATE_CONNECTING, STATE_DISCONNECTED, STATE_DISCONNECTING,

Returns
List<BluetoothDevice> List of devices. The list will be empty on error.
